Repairing a Victron Orion-Tr DC-DC Charger

I recently decided to make the switch to LiFeP04 for the second battery in the cruiser and eventually settled on a Victron Orion-tr Smart 12/12-18 to charge it.

While capacity testing the new battery on the bench I used a mess of random wire I had sitting around. Queue disaster. With my thinking obscured by the fog of a bad headache, I reversed the polarity when reconnecting the setup. The protection on the BMS kicked in, but not before the Victron was damaged.
